A circular coil of 1000 turns each with area 1 m 2 is rotated about its vertical diameter at the rate of one revolution per second in a uniform horizontal magnetic field of 0 . 07 T . The maximum voltage generation will be _____ V .
Correct answer
0
Step-by-step solution
Given, N = 1000 ,   A = 1   m 2   and B = 0 . 07   T The maximum emf generated is ε max = N B A ω , = N B A 2 π f = 1000 × 0 . 07 × 1 × 2 π 1 = 140 π Thus, maximum emf is 439 . 6   V ≈ 440   V .
